Explanation:

Identify the visible mathematical expression

$$ y = 3 $$

Determine the geometric representation

$$ \text{A horizontal line passing through } (0, 3) $$

Define key points for plotting

$$ (x, y) \in \{(-8, 3), (0, 3), (8, 3)\} $$

Answer:

The equation is \(y = 3\), which represents a horizontal line passing through all points where the \(y\)-coordinate is \(3\). To graph this on the coordinate plane, draw a straight horizontal line passing through the point \((0, 3)\) on the \(y\)-axis, extending from \(x = -8\) to \(x = 8\).
